The surface area of a cylinder is given by the equation 2πrexponet2 +2πrh, where r is the radius of the cylinder and h is the height of the cylinder. What is the surface area of a cylinder with the radius x-1 and height 2x?
The answer to the first question is D.)
The 6 in front of the parentheses modifies both 'x' and 3
The answer to the second question is D.)
When you plug 4 into the equation, you get 14
3(4) + 2 = 14
12 + 2 = 14
14=14
Hope this helps!
Answer:
x = 2
Step-by-step explanation:
-12 = -2x - 4x
-12 = - 6x
x = -12/(-6) = 2
A manager wants to test whether two normally distributed and independent populations have equal variances. the appropriate test statistic for this test is a "F-statistics."
<h3>
What is F-statistics?</h3>
An F statistic is a value obtained after performing an ANOVA test or even a regression analysis to determine whether the means of two populations differ significantly.
Some key features regarding the F-statistics are-
- It is comparable to a T statistic from the a T-Test; a T-test would then inform you when a single result is statistically significant, whereas a F test would then tell you if a set of variables is statistically significant.
- When determining whether your total results are significant, you must use the F statistic in conjunction with the p value. Why?
- A significant result does not imply that all of your variables have been significant.
- The statistic is simply comparing the cumulative influence of all the variables.
